Depth. Depth would be a useful differentiator. I need a few thousand words that actually teach me something, not three paragraphs that vaguely gesture in the direction of an idea.

THIS. My favorite example is Jeremy Cole’s blog [0], especially the stuff on InnoDB. You want to take a deep dive into the murky internals of MySQL? This is it. Tons of other stuff as well, but those are my favorite. He wrote tooling to visualize .ibd files FFS.

+1. Jeremy is well-informed and excellent at explaining technical topics. He and others like Jeremy Zawodny were major forces for good in the MySQL community back in the days of MySQL AB.

I agree. Depth creates much more evergreen content than just "news commentary" or similar.
